RTW and half-world route planning

Build a route that keeps moving around the planet.

List the places you want to stop, choose east or west, and see whether the trip looks like a true alliance round-the-world ticket or a smarter multi-ticket journey.

Route builder

Prefill your stop list, then tune the direction.

The planner uses city or airport names, estimates great-circle distance, counts segments, and flags whether a route looks more like an alliance RTW fare or a multi-ticket trip.

    Kiwi gets the first try because it can accept a generated multicity handoff and often finds creative separate-ticket routes. Skyscanner is added as a multicity price-discovery layer, currently capped to the first six legs, but it is still a meta-search handoff to airlines and booking sites. For formal RTW protection, validate and book on the alliance or airline site. Expedia and Trip.com are sent the first leg rather than a fragile fake full-route URL.

    Major RTW hubs

    Click airport dots or add a hub below.

    Added airports stay muted so the route-builder feedback is visible in real time. These are practical long-haul gateways, not every airport; alliance tickets still depend on direction, backtracking, seats, segments and mileage rules.

    Booking paths

    One trip, several ways to ticket it

    Kiwi

    Try the clever route first

    Best for creative multi-city and self-transfer combinations that normal airline or OTA searches may not build. Keep generous buffers and check baggage, check-in and airport-transfer details before paying.

    United / Star Alliance

    Book formal RTW fares here

    Often worth checking when the trip uses hubs like Singapore, Tokyo, Istanbul, Frankfurt, London, New York, San Francisco or Sydney, especially if benefits and change handling matter.

    American / oneworld

    Use the alliance builder for rules

    oneworld has RTW products such as continent-based Explorer and mileage-based Global Explorer, useful for premium or structured trips.

    Delta / SkyTeam

    Compare member airline routings

    Delta sits in SkyTeam, alongside airlines such as Air France-KLM, Korean Air, Vietnam Airlines, Garuda Indonesia and others.

    Flexibility

    Changes depend on the fare

    Many RTW tickets are built for date changes, but reroutes, cabin changes, no-shows, taxes and reissues can cost extra. Check the issuing airline or alliance rule sheet before relying on flexibility.

    Basic vs flexi

    Cheapest is not always safest

    Basic-style fares suit fixed plans. Flexi-style fares can be worth more on long trips where dates, stop lengths or work meetings may shift.

    Interruptions

    Ask before leaving the route

    If an emergency sends you home mid-trip, call the issuing airline or alliance desk before missing flights. They may be able to change dates or resume later, but no-shows can cancel the remaining ticket.

    Value test

    The discount needs to be real

    RTW wins when the fare saving, status earning, benefits, baggage protection or premium-cabin value beats the risk and rigidity. If the saving is small, separate tickets may feel calmer.

    Airport buffers

    Build in time for things to go wrong

    Traffic, long security lines, immigration, terminal transfers, remote gates and gate changes can all turn a legal connection into a stressful one. Price the buffer, not just the fare.

    Risk check

    Pick the booking path that matches the stakes

    Cheap and clever is excellent when the trip can bend. One-ticket protection matters more when the trip is expensive, tight, premium cabin, business-critical or hard to rebook.

    Kiwi / DIY

    Best for price and unusual routes

    Kiwi can stitch together flights that airlines do not sell as one itinerary. That is the point, and also the risk: a delay on one carrier may not oblige the next carrier to help if it is a self-transfer.

    Support

    Reviews are genuinely mixed

    Recent Kiwi reviews praise easy booking and prices, while complaints cluster around refunds, human escalation, baggage or check-in surprises. Treat support speed as a risk variable, not an afterthought.

    Kiwi Guarantee

    Protection is optional, not magic

    Kiwi says its protection can provide credit for replacement travel or assisted refunds after carrier disruptions, especially for self-transfer itineraries. Read the exact inclusions before relying on it.

    Expedia / OTA

    Mainstream, but still an intermediary

    Expedia is useful for simple price checks and packages, but its public flight deeplink does not reliably prefill a full RTW chain. Reviews also show support and refund friction when bookings go wrong.

    Alliance / airline

    Strongest for one-ticket continuity

    A formal alliance or airline-issued RTW ticket is usually better for missed protected connections, through baggage, status logic and date changes. It can be less flexible for clever routings and cheap one-off deals.

    No-show risk

    Never just skip a sector

    On airline tickets, later flights can be cancelled if earlier coupons are missed without a change. On separate tickets, one missed flight can leave every later booking untouched but unusable unless you can still reach it.

    Rule of thumb

    Match risk to trip value

    Use Kiwi when the saving is meaningful, you have time buffers and you can tolerate rework. Use alliance or airline ticketing when disruption, timing or support quality matters more than route cleverness.

    Ground links

    Surface legs need buffers too

    12Go-style train, bus and ferry links can make an itinerary better, but they rarely protect flights. Leave a night before expensive long-haul flights when ground transport is part of the chain.

    Cabin strategy

    Economy and premium need different thinking

    Economy

    Economy RTW fares can be beaten by multi-city and mixed-airline tickets, especially for half-world trips or routes with low-cost carriers.

    Premium economy

    Premium economy can make alliance fares more interesting when the itinerary has long sectors and you value one-ticket protection.

    Business or first

    Premium cabins are where formal RTW tickets sometimes become surprisingly competitive, but rules, availability and surcharges matter.

    Circle Pacific

    Pacific fares can be stricter than they look

    A city turning red in an alliance builder can mean the stop is unsupported for that fare, breaks direction logic, exceeds flight or stop limits, creates awkward backtracking, or has no valid Star Alliance flight combination for the dates.

    Three areas

    Asia, North America and South West Pacific

    Circle Pacific fares are built around those areas, so a route that feels sensible on a map still has to satisfy the fare's regional pattern.

    Required Asia stop

    Nadi and Honolulu are not Asia

    If the tool says the itinerary must include at least one stop in Asia, add a true Asia gateway such as Tokyo, Seoul, Taipei, Singapore, Bangkok or Hong Kong before returning to Australia.

    Supported gateways

    Not every airport qualifies

    Use alliance hubs first. A separate positioning flight may be needed from places like Darwin before starting the formal Circle Pacific or RTW ticket.

    Direction

    Tokyo or Honolulu may be off-course

    If the stop looks like a return across the same ocean, a second crossing, or a backtrack against the chosen direction, the planner may reject it without a friendly explanation.

    Flight caps

    Every coupon matters

    Connections, side trips and surface gaps can consume the allowance quickly. The cheapest-looking route may fail because it needs one extra flight.

    Availability

    Valid city, invalid date

    A city can be permitted by the fare but still turn red if the tool cannot build valid member-airline flights for the selected direction and dates.

    Workaround

    Save the route and ask support

    If the planner gives no reason, save the itinerary code and ask the alliance or issuing airline which rule failed before rebuilding the whole trip.

    Surface sectors

    Some of the best RTW legs are not flights

    Use trains, buses, ferries or one-way car rentals where they avoid backtracking or turn a rigid RTW fare into a better trip.

    Rail

    Good inside Europe and Japan

    Paris-London, Spain-Portugal, Italy-Switzerland and Japan city pairs can be cleaner overland than flying back through a hub.

    Bus or ferry

    Useful in Southeast Asia

    Thailand-Cambodia, Malaysia-Singapore, island routes and ferry-linked trips can keep the journey moving without adding a flight coupon.

    Booking check

    Compare before locking flights

    Tools like 12Go can help with train, bus and ferry options, but still check border rules, baggage, timing and whether the RTW fare counts the gap.

    Pace

    Year-long journey or one hard aviation sprint

    Classic travel

    Use the ticket across months

    The normal RTW pattern is slow enough to make the stopovers matter, with the whole journey often completed within about a year.

    Status run

    Fly it quickly for credits

    Some travellers compress a global loop into days or weeks for status credits, tier miles or cabin-value arbitrage. It can be clever and absurd at the same time.

    Hybrid

    Mix useful stops with earning logic

    A practical version uses a few genuine stops, then chooses alliance-friendly routings where the long sectors earn well.

    Who uses this

    Different travellers, different round-the-world logic

    Backpacker

    Many places, lower fare pressure

    Backpackers often mix cheap flights with overland travel, so a half-world or open-jaw route can beat a strict alliance RTW ticket.

    Retiree

    Comfort, time and fewer hard transfers

    Retirees may get more value from longer stopovers, fewer risky self-transfers and premium economy on the longest sectors.

    Business

    Several short stops, one clean ticket

    Business RTW trips can need quick city hops, reliable protection and alliance lounge/status logic more than the absolute cheapest fare.

    Rule sense-check

    What usually separates RTW from multi-ticket

    Direction

    Alliance RTW fares generally require continuous travel east or west between major zones, with limited backtracking.

    Oceans

    Formal RTW tickets usually need one Atlantic crossing and one Pacific crossing.

    Stops

    Alliance products commonly use minimum and maximum stopover rules, with transfers under 24 hours treated differently.

    Segments

    A maximum number of flight coupons or segments often applies, so surface legs and side trips matter.

    Surface gaps

    Train, ferry or self-arranged gaps can be useful, but an open-jaw gap may still count against sector, mileage, continent or direction rules.

    Mileage

    Some fares price or validate by mileage bands, so the shortest-looking route can still fail a rule.

    Start and finish

    Most true RTW fares need to finish in the same city or country where the trip began.

    Time limit

    Many RTW tickets are designed around completing travel within roughly one year, so long stays need date discipline.

    FAQ

    Round-the-world planning questions

    Does Expedia sell round-the-world tickets?

    Usually treat Expedia as a multi-city fare search rather than a formal RTW fare engine. It can still be useful for half-world and multi-ticket comparisons.

    Can I list stops and prefill a booking tool?

    This planner can build Kiwi and Skyscanner multicity handoffs from the route, with Skyscanner capped to the first six legs and best treated as meta-search price discovery. Expedia's official flight deeplink handles one-way or roundtrip searches, so the Expedia button uses the first leg rather than pretending to load a full RTW chain. Many alliance RTW builders also do not expose a reliable public URL that preloads every city.

    Is Kiwi safe for a round-the-world trip?

    It can be a very useful first check for price and creative routings, especially if your dates are flexible and you can build in long self-transfer buffers. The trade-off is that some Kiwi itineraries are separate tickets, so airline protection may not carry across a missed self-transfer, and review patterns show support/refund experiences can vary sharply.

    Can any airport be used on a round-the-world ticket?

    No. A formal RTW ticket generally needs airports and flights served by the participating alliance or fare partners, and the itinerary still has to pass direction, stopover, transfer, mileage, ocean-crossing and availability rules. A DIY multi-ticket trip can use more airports, but loses some one-ticket protection.

    Why does an alliance planner turn a city red?

    It may be the wrong airport for that product, an unsupported route order, too many flight coupons, too many or too few stopovers, a mileage problem, backtracking, a missing regional requirement, or simply no valid flights on the dates. Try changing direction, removing a side trip, starting from a bigger hub, or asking support which rule failed.

    Why would Tokyo or Honolulu fail on a Pacific fare?

    They can be valid Pacific gateways in some routings, but placement matters. Honolulu is not an Asia stop, and Tokyo only helps if the tool can place it in a valid direction with available flights and enough coupons. If the route is Australia-Nadi-North America-Honolulu-Australia, the planner may reject it because it still has no Asia stop.

    Why did Star Alliance reject Honolulu to Brisbane?

    In the Circle Pacific planner, a route through Nadi, Los Angeles, San Francisco and Honolulu can still fail if it has no stop in Asia. Try inserting a real Asia gateway before the return to Australia, then check whether the flight count and direction still validate.

    Can I leave a gap and take a train or ferry?

    Often yes, as an open-jaw or surface sector. Treat the gap as part of the fare test, though: some products count it as a sector or include its distance when checking the itinerary.

    Can I pause the trip and resume later?

    Sometimes, if the ticket validity, fare rules and airline change policy allow it. If you need to go home for an emergency, get the ticket reissued or protected before missing the next flight, because a no-show can cancel later sectors.

    Does missing one flight invalidate the rest of the ticket?

    It can. Airlines commonly require flight coupons to be used in sequence, so missing one sector without changing or cancelling it first may cancel the onward or return flights. Traffic, queues, checkpoints, large terminals and gate changes make this a real planning risk, not just a fine-print problem.

    When is a formal RTW ticket worth it?

    Usually when the discount, status credits, alliance benefits, checked-bag handling, premium cabin value or one-ticket protection is significant. If the price is close to separate tickets, the extra rigidity may not be worth it.

    What if I only go halfway around?

    That can be a good multi-ticket trip. The planner flags it separately because forcing a half-world trip into RTW fare rules can cost more and reduce flexibility.
